Airworthiness Directives; The Boeing Company Airplanes

We propose to supersede Airworthiness Directive (AD) 2016-04- 16, which applies to all The Boeing Company Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC-10-40, DC-10-40F, MD-10-10F, MD-10-30F, MD-11, and MD-11F airplanes. AD 2016-04-16 requires adding design features to detect electrical faults and to detect a pump running in an empty fuel tank. Since we issued AD 2016- 04-16, we have received new service information that would eliminate the need for certain provisions of AD 2016-04-16. This proposed AD would provide optional terminating action for certain requirements. We are proposing this AD to address the unsafe condition on these products.
